Fits good on a John Deere 3800 pressure washer. Can't use the pump at full capacity. It is stronger than the motor.

Pump works great 👍. Installed it on a GX390 clone and it fit perfectly. It doesn't reach the full 4000psi rating, I get about 3800/3900psi on the gauge. However it's fine for me because I don't need that much psi. So right now I have it set to 3400psi. The pump has a nice weight too it and the build quality is surprisely good.

Bolted right up to the Honda engine on my Dewalt pressure washer. I've only used it for maybe half an hour but so far it seems identical in performance to the original pump. Well the original pump barfed all its insides out a hole in the bottom, so the Vevor replacement is working significantly better than that.
